High-molecular-weight glutenin subunits (HMW-GSs) encoded by alleles at the Glu-A1, Glu-B1, and Glu-D1 loci confer unique end-use quality properties of common wheat (Triticum aestivum L.). Wheat accessions with high-quality HMW-GSs combination Ax2*/Bx7OE/Dx5 usually exhibit strong gluten characteristics. In order to stack these three subunit genes molecular markers in breeding, an agarose gel-b...

Abstract Background Wheat flour maturation affects the aggregation and structural stability of proteins. The number high-molecular-weight glutenin subunits (HMW-GSs) differs in various wheat varieties. effects Dx2 absence on protein characteristics thermal were investigated during 120 days using near-isogenic lines (NILs). Results delayed decreased flours maturation, i.e., maturation-induced in...

Wheat is the most essential food crop and taxonomically belongs to family poaceae. Bread wheat is a Hexapliod species with 2n=6x=42 chromosomes having high genetic diversity, the genetic variation enables plant species to adapt to changing environments and provide resistance against different diseases. The scientists are highly interested to study the genetic diversity among wheat varieties mor...

bread-making quality in hexaploeid wheat is a complex trait for breeding programs. high molecular weight glutenin subunits (hmw-gs) have an important effect on dough stability and elasticity. the glu-1 loci that are encoded these subunits are located on the long arms of group-1 homologues chromosomes of the a, b and d genomes. in this work we used pcr-based dna markers to distinguish wheat brea...

Four LMW-m and one novel chimeric (between LMW-i and LMW-m types) low-molecular-weight glutenin subunit (LMW-GS) genes from Aegilops neglecta (UUMM), Ae. kotschyi (UUSS), and Ae. juvenalis (DDMMUU) were isolated and characterized. Sequence structures showed that the 4 LMW-m-type genes, assigned to the M genome of Ae. neglecta, displayed a high homology with those from hexaploid common wheat. Th...

10 accessions of tetraploid wheat were radiated with 100 Gy (60)Co γ -ray. The germination energy, germination rate, special characters (secondary tillering, stalk with wax powder, and dwarf), meiotic process, and high-molecular-weight glutenin subunits (HMW-GSs) were observed. Different species has different radiation sensibility. With 1 seed germinated (5%), T. dicoccum (PI434999) is the most...

Wheat storage proteins of twelve winter wheat cultivars grown at the experimental field of the Agricultural Institute Osijek in 2009 were studied for their contribution to the baking quality. Composition of high molecular weight glutenin subunits (HMW-GS) was analyzed by SDS-PAGE method, while the proportions of endosperm storage proteins were determined by RP-HPLC method. Regarding the proport...

Low-molecular-weight glutenin subunits (LMW-GS), encoded by a complex multigene family, play an important role in the processing quality of wheat flour. Although members of this gene family have been identified in several wheat varieties, the allelic variation and composition of LMW-GS genes in common wheat are not well understood. In the present study, using the LMW-GS gene molecular marker sy...
